Help ID please it seems like a very fine dust , that covers my glass and easily blown off . It firsted started on the sand bed as a stringy like algae with oxygen bubbles , it’s now just grows on the glass as dust brown particles that sort of clump and certain areas of the sand bed as a stringy algae that is also easily blown off.
